NIST acquired a large amount of visual material as part of its World Trade Center Investigation. A subset of this material, including photographs and video clips, was organized into a searchable database in which each image and video clip was characterized by a set of attributes including: source/owner, time of shot/video, content (including building, face(s), key events such as plane strike, fireballs, collapse), and other details.
The process of organizing and assigning attributes to these images and video clips did not include assigning every possible appropriate attribute to every image and video clip in the database. Therefore, it is possible that some images and video clips in this collection may not be tagged with an attribute that is in fact appropriate for that image or video clip.
In addition, some of the photos and video clips contain information that was embedded by the camera or the photographer. NIST takes no position as to the accuracy of any such information.
